To all whom it may concern:

Be it known that we, PELEG ROSE and GEORGE C. ItosE, of Norwich, in thecounty of New London and State of Connecticut, have invented certain newand useful Improvement-s in Machines for Separatin g the Fibers of\Vood; and we do hereby declare that the following is a full, clear, andexact description of the inventi0n,which will enable others skilled inthe art to which it appcrtains to make and use the same, reference beinghad to the accompanying drawings, which form a part of thisspecification, and in which- Figure 1 is a View, in perspective, of amachine embodying the improvements of our in- Fig. 2 is a plan View.Fig. 3 is a side elevation, and Fig. 4 is a modification.

This invention relates to machines for separating the fibers of wood inthe manufacture of paper-pulp; and it consists in the improvements inthe construction of the machine, as hereinafter fully described, andparticularly pointed out in the claim.

In the accompanyin g drawings similar letters of reference indicatecorrcspondin g parts in the several figures.

Upon the rectangular base A is mounted the disk B, provided with shaft0, having beltpulley D. The faces of the disk B are provided with thescrapers E.

The rims F of the disk may be beveled, as in Fig. 4, and the scrapers Eplaced at any desired angle without departing from the spirit of ourintention.

Inclined chutes Gr are fixed to the base A, their inner ends comingalmost in contact with the edges of the scrapers E.

The wood to be reduced to fiber is fed to the scraper down the chutes C;but any suitable means for holding the wood in contact with the scrapersmay be substituted for the chutes.

*e do not claim a cutter or a series of the same, said cutters beingradically different in their working and results from the scraper orscrapers shown and described in our invention.

Having thus described our invention, what we claim as new and useful,and desire to secure by Letters Patent of the lnited States,

In a machine for separating the fibers of wood, the rotary disk 13,provided on its face or faces with the scrapers E, in connection withsuitable means for holding the wood in contact therewith, substantiallyas and for the purpose set forth.

In testimony that we claim the foregoing as our own we have heretoaftixed our signatures in presence of two witnesses.
